Here are the rings of the series "The 4 elements". The idea of giving shape to the 4 basic elements of all matter had long been in my mind. First I thought to a common shape, and then I gave them their own personalities,. I'll save you from telling a bit of philosophy on the 4 elements (which you can read at the product page), and I tell you that I really like this work I did, I hope you too. Thanks for reading.
